At a reception held at the Prime Minister's residence in honour of Pakistan's Champions Trophy victory, Pakistan Cricket Board (PCB) chairman Shaharyar Khan announced that he had offered the role to Sarfraz, who accepted it, reports ESPNcricinfo.

Pakistan trounced India by a record 180-run margin in the final at the Kennington Oval in London on June 18 to lift their maiden Champions Trophy title.
The wicketkeeper-batsman took over the T20I captaincy from all-rounder Shahid Afridi after the 2016 World T20 and became ODI captain when Azhar Ali resigned in February this year.
In January, it was announced that ODI captain Azhar Ali would lead the Test side following Misbah-ul-Haq's retirement as a part of "radical changes" required in the national team.
